Kiichi is a tall man with wavy long hair pulled back in a ponytail, and sports several scars on his face, both in vertical and horizontal patterns. He wears the typical clothes of the other former Gaun School warriors: a shirt with long sleeves and black shoulders with the Muhou Symbol right under it, belt and lightly colored hakama pants.
Not much is shown of Hasukawa's personality. He first shows joy at the prospect of fighting the Ogame School, but he does shows signs of concern when Arata's archers join the battle. However he's shown to be excessively overconfident, as he overlooked Gensai Kizaki as if he wasn't a threat.
At one point, Kiichi and the other members of the Gaun School joined the Muhou School, and he was promoted to Commander of the 5th Corps.
Ayanaka Forest ArcEdit
Hasukawa is seen with the other named members of the Gaun School (Furuhashi Genya and Yoshifuku Jingyou) and Ango as they prepare to enter Anayaka Forest. During the battle against Shinnojou and Iori he and the other Commanders keep an eye on the situation. Then, Gensai asks him if he can kill him since his guard is so full of openings. Kiichi tries to snark back, but Gensai kills him in a flash with a triple slash, much to his stupor.
Kiichi wields the nagamaki with the style of the Gaun School, and according to Shin he's more powerful compared to the other commanders. However, the full extent of his skills is unknown.

Despite being clearly introduced as "Hasukawa Kiichi" in chapter 106, later in chapter 111 the scanlation changes his name and rank to "Oshimi Taisuke" Commander of the 10th Corps. According to the Japanese Wikipedia article, Hasukawa is correct.
